Abstract
The cathode in a molten carbonate fuel cell (MCFC) was made using the tape casting method from a slurry with a suitable chemical composition consisting of porogen, allowing it to achieve a porous structure. Currently used porogens in creating cathode structures are synthetic polymers, which release hazardous substances into the environment during thermal removal. Therefore, it is very important to find a safer alternative before industrial production of fuel cells begins and reduce its impact on the environment. The research aimed to analyze the possibility of using various porogens to obtain a fuel cell's cathode microstructure and compare them to a reference cathode. The electrodes were produced using cheap, accessible, and natural porogens. Chosen porogens were post-production waste materials such as wheat straw, hemp, and beet pulp. They were used solo or coupled to create the cathode of MCFC, thoroughly characterized in the context of morphology, structure, and chemical composition. After optimization, final MCFC cathodes were characterized by SEM, Archimedes porosimetry, gas porosimetry, and gas permeability. The highest power density (100 mW/cm2) was obtained for the cathode, which was made with starch and straw, while starch and PVB enabled the achievement of 90 mW/cm2 of the MCFC cathode.
期刊介绍：
Energy is the single most valuable resource for human activity and the basis for all human progress. Materials play a key role in enabling technologies that can offer promising solutions to achieve renewable and sustainable energy pathways for the future.
Materials for Renewable and Sustainable Energy has been established to be the world''s foremost interdisciplinary forum for publication of research on all aspects of the study of materials for the deployment of renewable and sustainable energy technologies. The journal covers experimental and theoretical aspects of materials and prototype devices for sustainable energy conversion, storage, and saving, together with materials needed for renewable fuel production. It publishes reviews, original research articles, rapid communications, and perspectives. All manuscripts are peer-reviewed for scientific quality.
Topics include:
1. MATERIALS for renewable energy storage and conversion: Batteries, Supercapacitors, Fuel cells, Hydrogen storage, and Photovoltaics and solar cells.
2. MATERIALS for renewable and sustainable fuel production: Hydrogen production and fuel generation from renewables (catalysis), Solar-driven reactions to hydrogen and fuels from renewables (photocatalysis), Biofuels, and Carbon dioxide sequestration and conversion.
3. MATERIALS for energy saving: Thermoelectrics, Novel illumination sources for efficient lighting, and Energy saving in buildings.
4. MATERIALS modeling and theoretical aspects.
5. Advanced characterization techniques of MATERIALS
Materials for Renewable and Sustainable Energy is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct. Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavor. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice as detailed here: https://www.springer.com/us/editorial-policies
